Genesis 30:32-40

32Let me go through all your sheep today and remove every sheep that is speckled or spotted, every dark-colored sheep among the lambs, and the spotted and speckled among the female goats. Such will be my wages.

33In the future when you come to check on my wages, my honesty will testify for me. If I have any female goats that are not speckled or spotted, or any lambs that are not black, they will be considered stolen.”

34“Good,” said Laban. “Let it be as you have said.”

35That day Laban removed the streaked and spotted male goats and all the speckled and spotted female goats — every one that had any white on it — and every dark-colored one among the lambs, and he placed his sons in charge of them.

36He put a three-day journey between himself and Jacob. Jacob, meanwhile, was shepherding the rest of Laban’s flock.

37Jacob then took branches of fresh poplar, almond, and plane wood, and peeled the bark, exposing white stripes on the branches.

38He set the peeled branches in the troughs in front of the sheep — in the water channels where the sheep came to drink. And the sheep bred when they came to drink.

39The flocks bred in front of the branches and bore streaked, speckled, and spotted young.

40Jacob separated the lambs and made the flocks face the streaked sheep and the completely dark sheep in Laban’s flocks. Then he set his own stock apart and didn’t put them with Laban’s sheep.
